My invention relates to a new and useful improvement in a boiler cleaner, and particularly that class of boiler cleaners in which a cleaning uid is discharged from a rotatable blower unit in such manner as to clean the boiler tubes of soot and ashes.

One of the objects of the invention is the provision in a boiler cleaner of this class of means for simultaneously rotating or rocking a pair of blower units each of which is mounted upon a separate boiler.

Another cleaner of this class, of means for connecting rotatable units mounted on separate boilers so that the same may be free to move universally relatively to each other.

Another object is a provision in boiler cleanersof this class of means for rotating several blower units in a plurality of boilers from the same position.

Other objects will appear hereinafter.

The invention consists in theV combination and arrangement of parts 'hereinafter described and claimed. Y l The invention will be best understood by reference to the accompanying drawings, which form a partof this specilication and in which,

The invention is particularly adaptable for use in marine boilers7 whichv are installed in batteries and positioned so closely together thatthere is very little space between the individual boilers.- Owing to the compact method of installing marine boilers it is often impracticable to install the usual blower units in the alley way between the boilers so that the unitsmay be rota-ted or rocked manually. This is particularly true on account of the amount of space taken up by the ordinary blower unit heads and on account of thefact that there is often not sufficient clearance between the two boilers to permit the operator object is the provision in a boiler .munioates by means of pipes the lateral walls DETROIT, MICHIGAN, .A CORPORA- BOILER CLEANER `Serial No. 453,872.

1n order to overcome these diiculties an improved head, which would take lessV space becomes-necessary. Also, it is advisable to provide means whereby theunits may be rotated or rocked by thepoperator from some other point than the alley space between `the boilers; My invention is designed toovercome these difficulties and to provide -a novel and useful-means of operating a pair of blower units simultaneously.

have shown the invention as applied' to a pair of boilers 7 7 each of which is equipped with water tubes 8 communicating with water legs 8 and steam drum 9.

are positioned at advantageous points transversely to the water tubes 8 as will be readily understood by anyone skilled in the art. Each of these units is connected with a suitable source of steam supply from which the steam may be delivered when it is desired to clean the boiler. The steam is delivered to header 9 which comj 10 with heads 12 of the blower units, each of said units beingsupplied by its respective pipe 10, the flow of steam through which is controlled by a supply valve 11. Securely fastened to head 12 is tubular member 13 to which is fixedly attached a collar 14, said member 13 being positioned within the opening 18, formed in wall 15 of the boiler. Slidably positioned in member 13 is blower unit 16 which projects into the interior of the boiler setting and to the outer end of which is fixedly attaced a cap 17 which is provided in with openings 18 to permit the passage of steam from the interior of head A12 to interior of unit 16. Securely fastened to cap 17 is a shaft 19 which 'a cap 12 mounted on the head 12. A gland 12 serves to maintain packingv 19 in snug engagement with shaft 19 so as to prevent escape of steam around said shaft. The outer end of said lshaft is positioned in a socket formed in shaft'22 and is secured in said socket by means of a pin 21 inserted through said shaft and positioned in longitudinal elongated vslots formed in shaft 22. Shaft 22 is suitably connected by means of coupling 22 YThe unit comp prises perforated pipes which projects through` to operate the units by hand."V Consequently,

tion herein set forth to pipe 24. Mounted on shaft 22 is a sprocket or gear wheel 23. The pipe 24 extends across the alley way between the boilers and is connected by means of a suitable pin to a shaft 19a similar to the shaft 19, which serves to rotate or rock the corresponding blower unit in the opposite boiler. The connection of the pipe 24 to this shaft is made by means of a pin 21a in the end of the shaft, which pin engages in transversely extending diametrically opposed slots 2lb in the pipe 24, as shown. There is ample clearance for the shaft 19a where it fits in the pipe 24 thus permitting relative movement of the oppositely aligned boiler settings, without binding the blower unit driving means.

Mounted loosely upon a shaft 25 which is journaled in bearings mounted upon platform 27 and secured to boilers 7 and 7 are wheels 26 each of which is connected by means of a suitable chain 28 to one of the sprocket wheels 23.

When it is desired to clean the boilers, the valve 11 which controls the unit it is desired to operate, is opened and steam is admitted to the head. In operation, steam is generally admitted to a pair of co-ordinated heads, although this is not necessary. In order to rotate the unit the operator stands on platform 27 and rotates the corresponding sprocket wheel 26. It will be noted that the operator in rotating sprocket wheel 26, causes a rotation of blower units simultaneously.

The purpose of having the connection between the co-ordinated units as already described is to allow the movement of said units relatively to each other as contraction and expansion takes place. Inasmuch as this expansion and contraction is not uniform, the units will not always move relatively to each other in the same manner. This method of connection also provides against binding of the driving shafts tending to result from the possible longitudinal movement of the units within the boiler settings, and from relative movement of the two opposite boiler settings.

While I have illustrated and described the preferred form of construction I do not wish to be restricted to precise details of construcbut desire to avail myself of such modifications and changes as will come within the scope of the appended claims.

Having thus described my invention, which I claim is new and desire to secure by Letters Patent is:
